Ha. I just came here to start this same thread. It would have been way more interesting if harbaugh let the time tick. At some point the bills would have been forced to send the kick team out on third down. And if he called timeout with like 12 seconds it probably would have forced the bills to kick on third and would have at least gotten a kickoff.
Ok but it would have been a better strategy than what they did. I actually think just not calling the timeout and watching what the bills did would have been interesting.
